Cover 4 Rules

Match Players

Take anyone who comes through your zone.

If #2 goes in, push to MHC and yell "In"
If #2 goes out, settle and get eyes on #1
If #1 goes outside, settle and eyes on #2; alert for smash
If #1 goes inside, settle first then push to MHC. Be alert to #2

Corners

Read #1

If #1 goes vertical, he is your responsibility
If #1 goes inside, let him go and eyes on #2
If #1 settles in flat, settle with him. Make "Smash" call.

Safeties

Read #2

If #2 to your side goes vertical, he is your responsibility. Match player should pass him off after 10 yards.
If #2 to your side goes in, shade #1
If #2 to your side goes out, follow with over-the-top leverage. If there is no #3 when #2 goes out, Match player should take #2. However, #2 is still the Safeties' responsibility. If there is a #3, or he is slow to show, Match player takes #3 and Safety should get to #2 as fast as possible.
